The static pages are what you want, just go to 'Static Pages' and add a new Embedded Page. Those will automatically be wrapped in the template. By default, the links to them will show up in the help menu.
To create a new menu, use this:
http://forum.x-cart.com/showthread.php?t=19871
If you want to have the links to the static pages appear in this menu instead of the help menu, simply open up help.tpl and move this line of code to the new menu:
{include file="pages_menu.tpl"}
